Which commission is responsible for investigating sexual harassment cases at the federal level?

The Equal Employment Opportunity Commission (EEOC) is the federal agency responsible for enforcing laws against workplace discrimination, including sexual harassment. The EEOC investigates complaints from workers and determines whether there is enough evidence to proceed with legal action. This role is crucial as it aims to uphold the rights of employees and ensure a safe working environment free from discrimination and harassment.

The other options are focused on different aspects of labor or justice. For example, the Texas Commission on Human Rights operates at the state level and addresses issues within Texas specifically, while the U.S. Department of Justice handles broader criminal and civil rights issues. Occupational Safety and Health Administration (OSHA) primarily focuses on workplace safety and health regulations rather than discrimination. Thus, the EEOC is clearly designated to handle sexual harassment cases at the federal level, making it the appropriate choice here.
